The Oklahoma League of Women Voters is asking Gov. Brad Henry to vote no on a bill to require voters to present identification before casting their ballots.

"We strongly urge Governor Henry to veto this legislation,” said Gloria Caldwell, a spokeswoman for the league.

Henry is reviewing the legislation, said his spokesman, Paul Sund.

"But he shares the concerns voiced by the League of Women Voters, the American Association of Retired People and other respected, nonpartisan organizations that oppose voter identification laws,” Sund said.

The House earlier this week approved Senate Bill 4, Republican-backed legislation that would require voters to prove their identities by showing photo identification issued by a state, federal or tribal government, or the free voter ID card issued by their county election board.

Voters without the required identification could cast a provisional ballot after signing an identification statement under oath.

Henry, a Democrat, has until midnight Wednesday to act on the measure. If he does not act, SB 4, which passed the House 71-27 and cleared the Senate 25-21, becomes law.
